' INITED STATES TAYLOR MARTIN, OF STURMS MILLS, XVEST VIRGINIA.

CHURN.

SPECIFICATION forming part of Letters Patent No. 319,831, dated June Q, 1885.

Application filed March ll, 1885. (No model.)

2'0 (ZZZ whom it may concern:

Be it known that I, TAYLOR MARTIN, a citizen of the United States, and a resident of Sturms Mills, in the county of Marion and State of WVest Virginia, have invented certain new and useful Improvements in Ohurns; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference beinghad to the accompanying drawings, which form a part of this specification, in which- Figure 1 is a perspective view of my improved churn. Fig. 2 is a longitudinal vertical sectional view of the same. Fig. 3 is a cross-section. Fig. 4is an end view, and Fig. 5 is a perspective view of the dasher.

Similar letters of reference indicate corresponding parts in all the figures.

My invention has relation to that class of churns having adasher journaled horizontally within the churn-body, and having concavoconvex blades or wings at its extremes; and it consists in the improved construction and combination of parts of the same, as hereinafter more fully described and claimed.

In the accompanying drawings, the letter A indicates the churn-body, which is cylindrical and mounted between end pieces, B B, which form legs or supports 0.

The end pieces are provided at their upper ends with brackets D D, in the ends of which are formed bearings E, in which the driveshaft F is jonrnaled, and this drive-shaft is provided at one end with a crank, G, for turning it, and at its other end with a crank, H, to which a connecting-rod, I, is pivoted, while a fly-wheel, J, is secured upon the shaft inside of one of its bearings.

The lower end of the connecting-rod or pitman is pivoted to a lever, K, which is pivoted at its other end upon one of the end pieces of the churn-body, and a cogged segment, L, projects downward from the inner end of this leyer and meshes with a pinion, M, which is secured upon the outer end of a short shaft, N, journaled in a bearing, 0, in the end piece of the churn-body and provided with a polygonal inner end, P, projecting into the churn-body.

The top of the churn is formed with flaring flanges Q, between the upper edges of which the cover R rests, the said cover fitting into and covering the open top of the churn-body, and the cover is formed with perforations S S, for inserting a thermometer for ascertaining the temperature of the churn, for pouring water, either hot or cold, into the churn, or for any other purpose where it is'desired to communicate with the interior of the churn without removing the cover.

A trough, T, is secured to the under side 0 the cover under the said apertures, preventing the contents of the churn from splashing out through the perforations during operation, while allowing air to enter into the churn through the perforations.

U is the dasher, which consists of two end pieces forming halves of an ellipse, and one of these end pieces is formed with a casting, V, having a polygonal recess, W, for the reception of the polygonal end of the short shaft, while the other end piece is provided with a casting, X, having a round recess, Y, into which a pivot, Z, may fit, which pivot is secured projecting inward upon the upper end of a spring, A, secured at the bottom of the churn upon the inner side of the end piece, and having a certain amount of play toward the said end piece.

The dasher-blades B B are concavo-convex, forming portions of a cylinder-surface, and are secured to the curved ends of the end pieces of the dasher, and this dasher is placed into the churn, rocking with the bearing at one end upon the spring-cushioned pivot, and with the short shaft in its hearing at the other end, the central position of the dasher being with the concaves facing downward, and with the aperture in the middle of the dasher registering with the opening in the top of thechurn.

It will be seen that, as the drive-shaft is revolved by means of the crank, or by any other connection with power, the crank at the other end of the shaft will revolve, and through the pitman communicate rocking motion to the lever, which, through its segment, will communicate rocking motion to the pinion upon the short shaft, and through it to the dasher, which thus will beat against the cream in the churn with its concave faces, driving it toward v easily be removed through the aperture in the middle of the dasher.

Having thus described my invention, I claim and desire to secure by Letters Patent In a horizontal churn, the combination of the cylindrical churn-body having a bearing in one end piece, a spring secured at its lower end to the end piece of the churn, at the bottom of the same, and provided with an inwardly-projecting pivot at its upper end, central to the churn, a dasher composed of two end pieces formed in the shape of the halves of an ellipse and two dasher-blades forming parts of a cylinder-surface and secured at their ends to the curved ends of the end pieces of the dasher, the said end pieces having castings, one having a recess for the reception of any own I have hereunto affixed my signature in presence of two witnesses.
